1. 1. Communication of life cycle assessment results : life cycle key performance indicators

   Författare :Helena Nydahl; Thomas Olofsson; Anders P. Åstrand; Staffan Andersson; Åsa Wahlström; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life Cycle Assessment; Monetary Valuation; Climate Impact; Life Cycle Key Performance Indicators; Global Warming Potential; LCA-result communication; Interpretation of LCA-results; climate change; klimatförändringar;

   Sammanfattning : The global warming that we are on track for will result in a severe loss of natural capital leading to significant losses in economic capital when urban infrastructure is destroyed, agricultural productivity declines and poverty spread among other disasters. Climate change due to emissions does not only affect the polluter, the hazardous effects becomes evident on a global level. LÄS MER

3. 2. Energy simulation and life cycle costs : estimation of a building's performance in the early design phase

   Författare :Jutta Schade; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction Engineering and Management; Byggproduktion;

   Sammanfattning : Sustainable development and the protection of the environment are key issues in our society today. The building stock in Europe accounts for over 40% of the final energy consumption, CO2 emissions and generation of waste. A large part of the life cycle performance is determined early. LÄS MER

4. 3. Modelling Life Cycle Cost for Indoor Climate Systems

   Författare :Dennis Johansson; Institutionen för bygg- och miljöteknologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVAC; life cycle cost; energy; Energy research; Energiforskning; Byggnadsteknik; Building construction; indoor climate system; ventilation; maintenance; LCC;

   Sammanfattning : The indoor climate system, which serves a building with a proper indoor air quality and thermal comfort, has been predominantly designed based on the initial cost. A life cycle approach could improve both the economic and environmental performance since the energy use could decrease. LÄS MER

5. 4. Forest-Fuel Systems : Comparative Analyses in a Life Cycle Perspective

   Författare :Lisa Näslund Eriksson; Leif Gustavsson; Antti Asikainen; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forest fuels; recovery systems; transportation; cost; primary energy use; CO2 emission; forest-fuel potential; life cycle perspective; Environmental engineering; Miljöteknik;

   Sammanfattning : Forest fuels can be recovered, stored and handled in several ways and these different ways have different implications for CO2 emissions. In this thesis, comparative analyses were made on different forest-fuel systems. The analyses focused on the recovery and transport systems. LÄS MER

7. 5. Maintenance Consideration for Long Life Cycle Embedded System

   Författare :Xiaozhou Meng; Benny Thörnberg; Mattias O'Nils; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning :      In this thesis, the work presented is in relation to consideration to the maintenance of a long life cycle embedded system. Various issues can present problems for maintaining a long life cycle embedded system, such as component obsolescence and IP (intellectual property) portability. LÄS MER
